Trailing slash breaks routing in docs website

[mtanco]

Actual behavior

When a URL has a trailing slash, any internal links that are not explicit to the file fail.

Expected behavior

Page to render instead of 404

Steps To Reproduce

Click on Gallery in the second to last section of the below page

Works

https://h2oai.github.io/wave/docs/tutorial-monitor goes to https://h2oai.github.io/wave/docs/examples

Doesn't Work

https://h2oai.github.io/wave/docs/tutorial-monitor/ goes to https://h2oai.github.io/wave/docs/tutorial-monitor/examples

Proposed Solution (needs testing)

This seems to be a docusaurus problem and they suggest, for now, using .md extensions and relative paths.
We'll need to do a bulk-replace of all our local links [Gallery](examples) to use extensions and relative paths

@mtanco Even though we use the .md extension in URL if the user lands with a trailing / (i.e. examples/index.md/ ) then still the issue remains.

Here also using useBaseUrl function instead of markdown hyperlink will fix the problem.

<a href={useBaseUrl('docs/examples')}>Gallery</a>

@lo5 WDYT?

@dulajra It would be good to figure out a way to fix this using plain markdown, without useBaseUrl everywhere. This is a problem with docusaurus: facebook/docusaurus#3372

In docusaurus/packages/docusaurus/src/client/normalizeLocation.ts
any trailing /index.html is knocked off the path.
If you knock off any trailing / as well with
pathname = pathname.replace(/\/$/, '');
on line 23, this seems to fix this bug.

But I don't know whether this would break anything else.
But it does seem to me that if you want to normalize, then allowing both /foo/bar/ and /foo/bar doesn't seem to be a very good job of normalizing to me.
